- ANGLE-COCK HOLDER AND TRAIN-PIPE CLAMP. i 1

. Application filed March 27, 1922. Serial No. 546,997.

To all whom it may concern:

Be it known that I, GLEON, M. HANNAroRo, a citizen of the United States,residing at Richmond, in the county of Henrico and State of Virginia,have invented. a certain new and useful Improvement in Angle-CockHolders and Train-Pipe Clamps, ofwhich the following is afull, clear,and exact description.

The object of this invention is to provide a device conforming to M. C.B. or A. R. A. standards, for holding angle-cocks and clampingtrain-pipes of railway cars.

The invention consists of a holder divided longitudinally into two partsand adapted to engage the train-pipe and the angular (polygonal) end ofthe angle-cock, and to support the train-pipe, and to hold theangle-cock rigidly in adjusted position, the parts of the holder beingmovable toward each other to engage the train-pipe and angle-cock andthen fixed in position by U bolts anchored in a right-angled bracketwhich is fixed to the end sill or other end portion of the car. In orderto compensate for variations in the length of train-pipe ends, theholder elements may be capable of adjustment with relation to thebracket. In any case, the assembling and disassembling of the parts arereadily performed by merely removlng the U bolts.

The invention is susceptible of variation in construction andarrangement and there are here shown two such variations merely asillustrations, one of them having the holder of such length as to beengaged by both of the U bolts, and the other of such length as to beengaged by only one of them. Of course, these permissible variationsinclude differences in rolling stock and changes in standards ofequipment.

In the accompanying drawings illustrating the invention, in the severalfigures of which like parts are similarly designated, Figure 1 is a topplan view of the two-part holder with the parts slightly separated. Fig.2 is a front end view. Fig. 3 is a side assembly elevation, with theholder flange and the bracket broken out to expose the bolt openings inthese parts. Fig. 4 is a front elevation of the parts shown in Fig. 3,with the fore part in section on the line IVIV. Fig. 5 is a section onthe line V-V, Fig. 3. Fig. 6 is a side elevation of another form of theinvention.

train-pipe end. Y

Fig. 2 illustrates the front end of both of these constructions.

The. angle-cock holder is made in two parts -1 and 2, alike exceptingthat one is right-hand and the other lefthand. Each of these parts 1 and2 is provided with a bottom portion 3 corresponding in curvature withthe train pipe to be engaged and the wall 4 which rises substantiallyvertical so that such walls in opposite parts will be parallel, andthese bottom portions and walls form a trough to receive and engage thetrain pipe. The walls terminate in laterally extended horizontal flanges5, which are provided with longitudinally extending At the front theparts 3 and at are extended to form the halves of a polygonal pocket 7adapted to receive and engage the correspondingly shaped end or hex 8 ofthe usual angle-cock and to hold the angle-cock against accidentalmovement in all directions.

9 is an L-shaped or right-angled bracket, preferably made by bending apiece of plate metal, and having a vertical member and a horizontalmember, the vertical member being adapted to be riveted to the end sill10 or other end portion of a car, by means of any desired number ofrivets 11. The horizontal portion of the bracket is provided withcircular holes 12, which are adapted to register with the slots 6 in theflanges of the holder. When theholder parts 1 and 2 are placed alongsidea train-pipe 13 with their flanges underneath the horizontal portion ofthe bracket 9 and the holes 6 and 12 registering, then U-bolts M arepassed up 1 from beneath the holder through these holes and secured bymeans of the nuts 15 which may be secured by lock-nuts 16 or othermeans; The provision of the slots 6 permits of the longitudinaladjustmentof the holder to properly place it with. relation to the Aswill be v seen, two used in the illustration of the invention shown inFigs. 3 and 4, and both of these U-bolts engage the holder. Inasmuch asthe U-bolts are fashioned to engage a holder that closely hugs thetrain-pipe when it is assembled thereon, it will be seen that when theseU-bolts are drawn up into place, they will hold the holder parts ingiven position as ,well as serve to clamp the train-pipe in position.

U-bolts 14: are,

The holder members cannot escape longitudinally from the Ubolts, becausethe latter pass through the slots 6 in the flanges of the holdermembers.

A modification of the holder just de scribed is shown in Fig. 6, themain differences between the two being that the holder in Fig. 6 isshorter by approximately half than the holder shown in the other viewsof the drawing, and these holder members are provided with rear endbeads or flanges 17 which serve as a reinforce, and only one of theU-bolts engages the holder, while the other is in direct contact withthe train pipe 13, but otherwise the holder in Fig. 6 in itsconstruction, mode of application and operation is the same as thatpreviously described and the parts are correspondingly designated.

In both cases the angle-cock holder and the train-pipe are securely andadequately held, and the extension of the train-pipe as required by M.O. B. or A. R. A. standards is anticipated and provided for.

It will be noticed further that the depth of the cavity in the holderformed by the parts 3 and 4tis such as to receive the train-pipe whollywithin the horizontal level of the flanges 5, and that the horizontalportion of the bracket 9 rests on these flanges and therefore contactswith the upper portion of the train-pipe and so insures the desiredrigidity of the structure or assembly of parts.

What I claim is 1. An angle-cock holder, made in two longitudinallyseparable parts and having a pocket formation to receive and engage thehex of the angle-cock and a trough to receive and engage the train pipeand provided with laterally extended horizontal flanges, and asupporting bracket therefor, said bracket adapted to be carried by a carand having a horizontal portion to engage the top of a train pipe andthe holder flanges and to serve as a direct support for holding theangle-cock and train pipe rigidly and thereby prevent the angle-cockfrom moving forward, backward, and laterally, and hold the same inproper position.

2. An angle-cock holder, made in two longitudinally separable similarparts to engage the hex on the angle-cock and the contiguous parts ofthe train pipe, the line of division being parallel with the train-pipe,

each of said two parts provided with a flanged portion at the topextending out laterally from the train-pipe and on a line with the topthereof and provided with longitudinal slots, combined with a supportdepending from the car and having a horizontal portion overlying and incontact with the train pipe and provided with bolt-holes with which theslots in the flanged portions may be alined, and U-bolts applied to theholder and train-pipe and having their ends extending through the slotsand bolt-holes, said slots permitting the adjustment of the holdermembers to the support to insure alinement.

3. An angle-cock holder, made in two longitudinally separable similarparts to engage the hex on the angle-cock and the contiguous parts ofthe train pipe, the line of division being parallel with the train-pipe,each of said two parts provided with a flanged portion at the topextending out laterally from the train-pipe and on a line with the topthereof and provided with bolt holes, combined with an L-shaped bracketadapted to be applied to the end of a car and having its horizontalportion in contact with the upper portion of the train pipe and providedwith bolt holes, and U-bolts applied to the holder and trainpipe andengaged with the bracket.

4. An angle-cock holder, made in two longitudinally separable similiarparts to engage the train pipe, the line of division being parallel withthe train-pipe, each part pro-' vided with a flanged portion at the topextending out laterally from the train-pipe and on a line with the topof the train-pipe and provided with bolt holes, the parts having apolygonal pocket to receive, engage and hold the angle-cock, an L-shapedbracket adapted to be applied to the end of a car and having itshorizontal portion overlying the train-pipe in the line of the holder,and U-bolts for connecting the holder parts with one another about thetrain-pipe and with the bracket and also binding the train-pipe andbracket together.

In testimony whereof I have hereunto set my hand this 24; day of March,A. D.
